A problem related to the system according to the related art will bebriefly described before an exemplary embodiment of the presentdisclosure is described. No specific operation method based on theremote operation has been disclosed with regard to the componentmounting systems according to the related art including that disclosedin PTL 1, and there is room for improvement in a case where an actualoperation is assumed in which the on-site operation by the field workerand the remote operation from the management device by the remote workerare carried out along with each other with respect to the processingdevice constituting the component mounting line.

Hereinafter, one exemplary embodiment of the present disclosure will bedescribed in detail with reference to accompanying drawings. Theconfigurations, shapes, and the like described below are examples fordescriptive purposes and can be appropriately changed in accordance withspecifications of component mounting systems. In the followingdescription, the same reference numerals will be used to refer toelements common to all the drawings so that the same description doesnot have to be repeated.

A configuration of component mounting system 1 will be described firstwith reference to FIG. 1. Component mounting system 1 is configured toconnect component mounting line L1 with communication network 2 andentire component mounting system 1 is configured to be controlled bymanagement computer 3. Board supply device M1, solder printing deviceM2, post-solder printing inspection device M3, board delivery device M4,component mounting devices M5 to M8, board delivery device M9,post-component mounting inspection device M10, reflow device M11, andboard recovery device M12 are connected in series from an upstream sidetoward a downstream side in a board transport direction to constitutecomponent mounting line L1.

In thismanner, board supply device M1, board delivery devices M4 and M9, andboard recovery device M12 supply, deliver, and recover the board inrelation to processing devices MP (described later) without executing awork for component mounting with respect to the board transported incomponent mounting line L1. Solder printing device M2 executes a solderprinting work (work for component mounting), in which a solder isprinted onto the board as the mounting target by a solder printingworking unit (working unit).

Post-solder printing inspection device M3 executes a post-solderprinting inspection work (work for component mounting), in which a stateof the solder printed onto the board is inspected by a post-solderprinting inspection working unit (working unit) including a solderinspection camera. Each of component mounting devices M5 to M8 executesa component mounting work (work for component mounting), in which thecomponent is placed onto the board by a component mounting working unit(working unit). Post-component mounting inspection device M10 executes apost-component mounting inspection work (work for component mounting),in which a state of the component placed on the board is inspected by apost-component mounting inspection working unit (working unit) includinga component inspection camera. Reflow device M11 executes a boardheating work (work for component mounting), in which the board movedinto the device is heated by a board heating unit (working unit), thesolder on the board is cured, and an electrode portion of the board isbonded to the electronic component.

Each of solder printing device M2, post-solder printing inspectiondevice M3, component mounting devices M5 to M8, post-component mountinginspection device M10, and reflow device M11 has device buzzer 4 andsignal tower 5. A main function of device buzzers 4 is to notify a fieldworker of device error occurrence in the respective devices by using asound, the field worker performing various works such as deviceoperations and component supply in component mounting line L1. Signaltowers 5 function to notify the field worker of device errors in therespective devices by using a visual expression such as turning on,turning off, and blinking of a signal lamp.

As described above, solder printing device M2, post-solder printinginspection device M3, component mounting devices M5 to M8,post-component mounting inspection device M10, and reflow device M11 areprocessing devices MP that execute the works for component mounting withthe working units with respect to the board transported in componentmounting line L1. In other words, component mounting system 1 includescomponent mounting line L1, in which the plurality of processing devicesMP (solder printing device M2, post-solder printing inspection deviceM3, component mounting devices M5 to M8, post-component mountinginspection device M10, and reflow device M11) are connected toconstitute component mounting line L1, and management computer 3(management device) connected to component mounting line L1 bycommunication network 2 (network).

In component mounting system 1, the solder printing work, thepost-solder printing inspection work, the component mounting work, thepost-component mounting inspection work, and the board heating work areexecuted in this order by processing devices MP with respect to theboard transported in component mounting line L1, and then a mountingboard on which the component is mounted via the solder is manufactured.

Component mounting line L1 is not limited to the configuration describedabove, and the number of component mounting devices M5 to M8 may be oneor may be five or more. In addition, component mounting system 1 may beconfigured for a plurality of component mounting lines L1 to becontrolled by single management computer 3.

Hereinafter, configurations of component mounting devices M5 to M8 willbe described with reference to FIG. 2. Component mounting devices M5 toM8 are similar in configuration to one another, and only componentmounting device M5 will be described below. Component mounting device M5has built-in device buzzer 4 and signal tower 5 is provided on an uppersurface of component mounting device M5. Operation panel P is disposedin an upper right portion of a front surface of component mountingdevice M5, where the field worker performs a field work. Touch panel 6and various operation buttons B are disposed on operation panel P. Touchpanel 6 has a display function for displaying an operation screen forcomponent mounting device M5 and the like in a liquid crystal panel andan input function for input of a command, various types of information,and the like based on an operation of the displayed operation screen.

Operation buttons B include start button B1, stop button B2, acquisitionbutton B3, and emergency stop button B4. Once start button B1 isoperated, component mounting device M5 initiates the component mountingwork (operation). Once stop button B2 is operated, component mountingdevice M5 stops the component mounting work (operation). Onceacquisition button B3 is operated, on-site operation right RL (describedlater) is acquired and an on-site operation such as an operation ofcomponent mounting device M5 based on touch panel 6 becomes possible.Once emergency stop button B4 is operated, power supply to componentmounting device M5 is disconnected and component mounting device M5 isemergency-stopped.

Safety cover 7 for protection is provided in a central upper portion ofthe front surface of component mounting device M5 and safety cover 7 isfor the field worker not to touch by mistake movable portions, such as amounting head (not illustrated) placing the component onto the board anda head movement mechanism (not illustrated) for a horizontal movement ofthe mounting head, while component mounting device M5 is in operation. Asensor (not illustrated) detecting opening and closing of the safetycover is disposed in component mounting device M5 and the opening andclosing of the safety cover is monitored with an output signal from thesensor.

Batch replacement carriage 9, which holds a plurality of tape feeders 8(component supply devices) in parallel thereon, is installed in acentral lower portion of the front surface of component mounting deviceM5 (below safety cover 7). Tape feeder 8 supplies component mountingdevice M5 with the component housed in a component supply tape. Tapefeeders 8 held by batch replacement carriage 9 and component mountingdevice M5 are electrically connected in a state where batch replacementcarriage 9 is installed in component mounting device M5. A state ofattachment and detachment of tape feeder 8 to and from componentmounting device M5 is monitored based on an electrical connection statebetween component mounting device M5 and tape feeder 8.

Batch replacement carriage 9 can be attached to or detached fromcomponent mounting device M5. The field worker performs the followingpreparation work on batch replacement carriage 9 in a state where batchreplacement carriage 9 is removed from component mounting device M5, thepreparation work being for installation of tape feeders 8 supplying thecomponent used for the component mounting work. During a change in setupof component mounting line L1, the field worker can batch-replace tapefeeders 8 by removing installed batch replacement carriage 9 andinstalling prepared batch replacement carriage 9. A sensor (notillustrated) detecting the attachment and detachment of batchreplacement carriage 9 is disposed in component mounting device M5 and astate of the attachment and detachment of batch replacement carriage 9is monitored with an output signal from the sensor.

Tape feeder 8 can be replaced even in a state where batch replacementcarriage 9 is installed in component mounting device M5. In this manner,the mounting head, the head movement mechanism, and tape feeders 8constitute the component mounting working unit in component mountingdevice M5, the component mounting working unit executing the componentmounting work for component placement on the board.

Hereinafter, a configuration of a control system for component mountingsystem 1 will be described with reference to FIG. 3. The followingdescription will cover a control system for processing devices MPexecuting the works for component mounting in component mounting system1 and management computer 3 connected to component mounting line L1 bycommunication network 2 and performing an overall control on componentmounting system 1 with processing devices MP being connected toconstitute component mounting line L1. Solder printing device M2,post-solder printing inspection device M3, component mounting devices M5to M8, post-component mounting inspection device M10, and reflow deviceM11, which are processing devices MP, constitute similar control systemsexcept that working units 21 executing the works for component mountingare the solder printing working unit, the post-solder printinginspection working unit, the component mounting working unit, thepost-component mounting inspection working unit, and the board heatingunit, respectively. In the following description, component mountingdevice M5 will be described as a representative of processing devicesMP.

Processing device MP (component mounting device M5) has work controlunit 20, working unit 21, device storage unit 22, device monitoring unit23, device side notification control unit 24, input unit 25, displayunit 26, device buzzer 4, signal tower 5, and communication unit 27.Work control unit 20 controls the work for component mounting byprocessing device MP by controlling working unit 21 based on data forcomponent mounting stored in device storage unit 22. In other words,work control unit 20 controls the solder printing work in solderprinting device M2, the post-solder printing inspection work inpost-solder printing inspection device M3, the component mounting worksin component mounting devices M5 to M8, and the post-component mountinginspection work in post-component mounting inspection device M10.

Device storage unit 22 stores error information 22 a and operation rightinformation 22 b in addition to the data for component mounting.Information on whether that processing device MP holds on-site operationright RL or management computer 3 holds remote operation right RR isstored in operation right information 22 b. On-site operation right RLrefers to a right with which the field worker can perform the on-siteoperation in that processing device MP. Remote operation right RR refersto a right with which a remote worker can remotely operate processingdevice MP at management computer 3 (management device) and viacommunication network 2, the remote worker mainly performing anoperation work at management computer 3 away from processing device MP.

Device monitoring unit 23, which monitors an operation state of workingunit 21 of processing device MP, an inspection result, output signalsfrom various sensors, and the like, stores the device error in errorinformation 22 a and transmits the device error to management computer 3via communication unit 27 once the device error is detected. Examples ofthe device error in component mounting device M5 include a componentshortage error that occurs when the component supplied by tape feeder 8is used up, a board position deviation error that occurs when thetransported board stops at a position deviating from a predeterminedboard stop position, and a component recognition error that occursduring non-detection of a component expected to be held by a suctionnozzle. Those detected as the device errors include a solder inspectionerror in post-solder printing inspection device M3 and a mountinginspection error in post-component mounting inspection device M10, theformer occurring when the printed solder is not in compliance with apredetermined shape standard and the latter occurring when the componentis not at a predetermined position on the board.

In addition, device monitoring unit 23 monitors whether a predeterminedspecific operation set in advance with respect to the processing devicehas been performed or not. When it comes to component mounting deviceM5, the specific operation is an operation relating to safety of thefield worker, examples of which include the opening and closing ofsafety cover 7, the operation of stop button B2, the operation ofemergency stop button B4, an attachment and detachment operation forinstalled tape feeder 8 (component supply device), and an attachment anddetachment operation for batch replacement carriage 9. Once the specificoperation is detected, device monitoring unit 23 transmits a signal forreporting to that effect to management computer 3 via communication unit27.

Device side notification control unit 24 controls notificationoperations by device buzzer 4 and signal tower 5 in accordance with anotification pattern transmitted from management computer 3. Device sidenotification control unit 24 performs the sound-based notification bycontrolling device buzzer 4 (first notification unit). Processing deviceMP may have a chime, a siren, or the like as the first notification unitinsofar as it is capable of performing the sound-based notification. Inaddition, device side notification control unit 24 performs the visualexpression-based notification (such as the turning on, turning off, andblinking of the signal lamp) by controlling signal tower 5 (secondnotification unit). Furthermore, device side notification control unit24 is capable of performing the visual expression-based notification bycontrolling display unit 26, examples of which include blinking of adisplay screen of display unit 26. Processing device MP may have arevolving light, a flash lamp, or the like as the second notificationunit insofar as it is capable of performing the visual expression-basednotification.

Regarding the specific operation, device side notification control unit24 performs the notification by signal tower 5 (second notificationunit) without performing the notification by device buzzer 4 (firstnotification unit) once a first notification pattern instructed bymanagement computer 3 is received during notification of remote responseerror ER (described later). During notification of on-site responseerror EL (described later), device side notification control unit 24performs the notification by each of device buzzer 4 (first notificationunit) and signal tower 5 (second notification unit) once a secondnotification pattern instructed by management computer 3 is received.

Input unit 25, which is an input device such as a keyboard, a touchpanel, and a mouse, is used during operation command and data input bythe field worker. In component mounting device M5, input unit 25 is theinput function of touch panel 6. Display unit 26, which is a displaydevice such as a liquid crystal panel, performs display of variousscreens such as an operation screen for the on-site operation by inputunit 25. In component mounting device M5, display unit 26 is the displayfunction of touch panel 6. Communication unit 27, which is acommunication interface, performs signal exchange with other processingdevices MP and management computer 3 via communication network 2(network).

Management computer 3 in FIG. 3 has management control unit 30,management storage unit 31, remote operation control unit 32, error typedetermination unit 33, operation right setting unit 34, operationmonitoring unit 35, management side notification control unit 36, inputunit 37, display unit 38, management buzzer 39, and communication unit40. Input unit 37, which is an input device such as a keyboard, a touchpanel, and a mouse, is used during operation command and data input, theremote operation of processing device MP, and the like. Display unit 38,which is a display device such as a liquid crystal panel, displays notonly various types of data but also an operation screen of eachprocessing device MP for the remote operation and the like. Managementbuzzer 39 functions to notify the remote worker of the device error ofprocessing device MP and the like by using a sound. Communication unit40, which is a communication interface, performs signal and dataexchange with processing device MP via communication network 2.

Management control unit 30, which is a calculation device such as a CPU,controls component mounting system 1 based on information stored bymanagement storage unit 31. Management storage unit 31, which is astorage device, stores error information 31 a and operation rightinformation 31 b as well as component mounting data. The device erroroccurring in each processing device MP and detected and transmitted bydevice monitoring units 23 of respective processing devices MP is storedin error information 31 a in association with respective processingdevices MP. Information on whether that processing device MP holdson-site operation right RL or management computer 3 holds remoteoperation right RR for that processing device MP is stored in operationright information 31 b with regard to each processing device MP.

Remote operation control unit 32 displays the operation screen of eachprocessing device MP in display unit 38 of management computer 3 withrespect to the plurality of processing devices MP holding remoteoperation right RR and controls those processing devices MP viacommunication network 2 such that those processing devices MP can beremotely controlled by input unit 37 of management computer 3. In otherwords, remote operation control unit 32 allows each of the plurality ofprocessing devices MP to be remotely controlled via communicationnetwork 2 (network) by input unit 37 (input unit) in management computer3 (management device).

An example of the operation screen of processing device MP for theremote operation that is displayed in display unit 38 of managementcomputer 3 will be described below with reference to FIG. 4. Operationscreen 52 for the remote operation of component mounting device M5 incomponent mounting line L1 is displayed on display screen 51 of displayunit 38 according to FIG. 4. Screen display frame 53 and various remoteoperation switches S are displayed on operation screen 52. Character 53a (“L1-M5” herein) identifying processing device MP subjected to theremote operation is displayed in an upper left portion of screen displayframe 53. The same screen information as screen information displayed ontouch panel 6 (refer to FIG. 2) of component mounting device M5 isdisplayed in screen display region 53 b in screen display frame 53.

Remote operation switches S include remote start switch S1, remote stopswitch S2, and remote acquisition switch S3. Remote operation switches Scorrespond to respective operation buttons B of component mountingdevice M5. In other words, an operation similar to that performed duringthe operation of start button B1 in component mounting device M5 isexecuted once remote start switch S1 displayed on operation screen 52 isoperated by input unit 37 of management computer 3. Likewise, anoperation similar to that performed during the operation of stop buttonB2 is executed in component mounting device M5 once remote stop switchS2 is operated and an operation similar to that performed during theoperation of acquisition button B3 is executed in component mountingdevice M5 once remote acquisition switch S3 is operated.

The remote worker can remotely operate component mounting device M5(processing device MP) by operating the operation screen for componentmounting device M5 and each of remote operation switches S displayed onoperation screen 52 of management computer 3 with input unit 37 (inputunit) of management computer 3 (management device). As described above,component mounting system 1 includes component mounting line L1, inwhich the plurality of processing devices MP are connected to constitutecomponent mounting line L1, and the management device (managementcomputer 3) connected to component mounting line L1 by the network(management network 2) and each of the plurality of processing devicesMP can be remotely operated via the network by the input unit (inputunit 37) of the management device.

Error type determination unit 33 in FIG. 3 determines the type of thedevice error (error) occurring in processing device MP, such as whetherthe device error of each processing device MP stored in errorinformation 31 a is remote response error ER or on-site response errorEL. Remote response error ER is a device error to which the remoteworker can respond by the remote operation based on management computer3. On-site response error EL is a device error that can be responded toonly by the field worker performing the on-site operation on processingdevice MP, examples of which include a device error entailing theopening and closing of safety cover 7 and a device error entailingattachment and detachment of the component supply device in errorprocessing. In other words, error type determination unit 33 determineswhether or not the device error (error) occurring in processing deviceMP is remote response error ER, which is an error of a target that isresponded to by the remote operation based on management computer 3(management device).

Remote response errors ER occurring in component mounting devices M5 toM8 include the board position deviation error imaged and recognized by aboard recognition camera and the component recognition error imaged andrecognized by a component recognition camera. Remote response error ERoccurring in post-solder printing inspection device M3 includes thesolder inspection error imaged and recognized by the solder inspectioncamera. Remote response error ER occurring in post-component mountinginspection device M10 includes the mounting inspection error imaged andrecognized by the component inspection camera. These remote responseerrors ER can be eliminated by the same images as images captured by therespective cameras and displayed in display units 26 of respectiveprocessing devices MP being displayed in display unit 38 of managementcomputer 3 and the remote worker performing an appropriate remoteoperation after grasping the situation.

On-site response errors EL occurring in component mounting devices M5 toM8 include the component shortage error regarding tape feeder 8. On-siteresponse error EL also includes a device error previously determined asremote response error ER but changed into on-site response error ELbased on a determination by the remote worker. Examples thereof includea case where the component recognition error that used to be remoteresponse error ER is changed into on-site response error EL by theremote worker viewing an image displayed in display unit 38 ofmanagement computer 3 and determining it as a component drop error inwhich the component is not held by the suction nozzle and a field workis required due to a possibility of the component being dropped incomponent mounting devices M5 to M8.

Operation right setting unit 34 in FIG. 3 updates operation rightinformation 31 b of management computer 3 and operation rightinformation 22 b of processing device MP based on the type of the deviceerror determined by error type determination unit 33. Specifically,operation right setting unit 34 updates operation right information 31 bof management computer 3 and operation right information 22 b ofprocessing device MP by setting remote operation right RR of managementcomputer 3 with respect to that processing device MP in a case where thedevice error determined by error type determination unit 33 is remoteresponse error ER.

In other words, operation right setting unit 34 has a function ofsetting remote operation right RR with respect to management computer 3(management device), remote operation right RR allowing a state to beachieved where the remote operation of processing device MP can beperformed by input unit 37 (input unit) of management computer 3(management device), and operation right setting unit 34 sets remoteoperation right RR with respect to management computer 3 (managementdevice) in a case where the error determined by error type determinationunit 33 is remote response error ER.

In a case where the device error determined by error type determinationunit 33 is on-site response error EL, operation right setting unit 34releases remote operation right RR of management computer 3 with respectto that processing device MP. Then, operation right setting unit 34 setson-site operation right RL for that processing device MP and updatesoperation right information 31 b of management computer 3 and operationright information 22 b of processing device MP.

In the case of a request for an operation (on-site operation) by inputunit 25 (input unit) of processing device MP based on, for example, anoperation of acquisition button B3 of processing device MP in a statewhere remote operation right RR is set with respect to managementcomputer 3 (management device), operation right setting unit 34 releasesremote operation right RR set with respect to management computer 3(management device). Then, operation right setting unit 34 sets on-siteoperation right RL for that processing device MP and updates operationright information 31 b of management computer 3 and operation rightinformation 22 b of processing device MP.

In a case where it is detected by device monitoring unit 23 ofprocessing device MP that the specific operation set in advance withrespect to processing device MP has been performed in a state whereremote operation right RR is set with respect to management computer 3(management device), operation right setting unit 34 releases remoteoperation right RR set with respect to management computer 3 (managementdevice). Then, operation right setting unit 34 sets on-site operationright RL for that processing device MP and updates operation rightinformation 31 b of management computer 3 and operation rightinformation 22 b of processing device MP.

While remote operation right RR is set for management computer 3,operation monitoring unit 35 in FIG. 3 measures and monitors idle timeTA during which the remote worker executes no remote operation based onmanagement computer 3 with respect to processing device MP, that is, thelength of time elapsed since a final remote operation. Once idle time TAexceeds predetermined time, operation right setting unit 34 releasesremote operation right RR set with respect to that processing device MP.In other words, operation right setting unit 34 releases remoteoperation right RR in a case where no remote operation based onmanagement computer 3 (management device) is performed for apredetermined period of time (predetermined idle time TA). Then,operation right setting unit 34 sets on-site operation right RL for thatprocessing device MP and updates operation right information 31 b ofmanagement computer 3 and operation right information 22 b of processingdevice MP.

Management side notification control unit 36 provides an instructionregarding a predetermined notification pattern for device sidenotification control unit 24 of processing device MP and controlsnotification operations by management buzzer 39 and display unit 38 ofmanagement computer 3 based on the device error determined by error typedetermination unit 33. Management side notification control unit 36performs the sound-based notification by controlling management buzzer39 (third notification unit). Management computer 3 may have a chime, asiren, or the like as the third notification unit insofar as it iscapable of performing the sound-based notification.

In addition, management side notification control unit 36 performs thevisual expression-based notification, such as blinking of display screen51 of display unit 38 in whole or in part, by controlling display unit38 (fourth notification unit). Management computer 3 may have a signaltower, a revolving light, a flash lamp, or the like as the fourthnotification unit insofar as it is capable of performing the visualexpression-based notification.

Regarding the specific operation, once it is determined by error typedetermination unit 33 that the device error is remote response error ER,management side notification control unit 36 provides an instruction ofthe first notification pattern for device side notification control unit24 of processing device MP in which the device error has occurred. Then,management side notification control unit 36 performs the notificationby each of management buzzer 39 (third notification unit) and displayunit 38 (fourth notification unit).

Once it is determined by error type determination unit 33 that thedevice error is not remote response error ER but on-site response errorEL, management side notification control unit 36 provides an instructionof the second notification pattern for device side notification controlunit 24 of processing device MP in which the device error has occurred.Then, management side notification control unit 36 performs neither thenotification by management buzzer 39 (third notification unit) nor thenotification by display unit 38 (fourth notification unit).

In this manner, device buzzer 4 (first notification unit) and signaltower 5 (second notification unit) of processing device MP andmanagement buzzer 39 (second notification unit) and display unit 38(fourth notification unit) of management computer 3 are notificationunits AM notifying of the occurrence of the error in processing deviceMP based on a result of the determination by error type determinationunit 33. Notification units AM perform the notification in the firstnotification pattern in a case where the error occurring in processingdevice MP is remote response error ER and perform the notification inthe second notification pattern in a case where the error is not remoteresponse error ER but on-site response error EL.

In other words, notification units AM have at least the firstnotification unit (device buzzer 4) disposed in each processing deviceMP and performing the sound-based notification and second notificationunit (signal tower 5) disposed in each processing device MP andperforming the visual expression-based notification, and thenotification by the second notification unit is performed and thenotification by the first notification unit is not performed in thefirst notification pattern whereas the notification is performed by eachof the first notification unit and the second notification unit in thesecond notification pattern.

Notification units AM also have the third notification unit (managementbuzzer 39) disposed in the management device (management computer 3) andperforming the sound-based notification and the fourth notification unit(display unit 38) disposed in the management device (management computer3) and performing the visual expression-based notification, and thenotification is performed by each of the third notification unit and thefourth notification unit in the first notification pattern whereasneither the notification by the third notification unit nor thenotification by the fourth notification unit is performed in the secondnotification pattern.

Hereinafter, a first example of a component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 5. The firstexample of the system operation method is an appropriate notificationcontrol method for device error response. Once the device error isdetected by device monitoring unit 23 of processing device MP, errortype determination unit 33 of management computer 3 determines whetheror not the device error is remote response error ER (ST1: error typedetermination process). In other words, error type determination unit 33determines whether or not the device error occurring in processingdevice MP is remote response error ER, which is the device error of thetarget that is responded to by the remote operation based on themanagement device (management computer 3).

In a case where the type of the device error is remote response error ER(Yes in ST1), notification units AM perform the notification in thefirst notification pattern (ST2: first notification process).Specifically, notification units AM do not perform the notification bydevice buzzer 4 (first notification unit) of processing device MP,perform the notification by signal tower 5 (second notification unit),and perform the notification by management buzzer 39 (third notificationunit) and display unit 38 (fourth notification unit) of managementcomputer 3. In other words, in the first notification pattern,processing device MP performs the visual expression-based notificationwithout performing the sound-based notification and management computer3 (management device) performs the sound-based notification and thevisual expression-based notification.

In a case where the type of the device error is not remote responseerror ER but on-site response error EL, (No in ST1), notification unitsAM perform the notification in the second notification pattern (ST3:second notification process). Specifically, notification units AMperform the notification by device buzzer 4 (first notification unit)and signal tower 5 (second notification unit) of processing device MPand perform neither the notification by management buzzer 39 (thirdnotification unit) of management computer 3 nor the notification bydisplay unit 38 (fourth notification unit) of management computer 3.

In other words, in the second notification pattern, processing device MPperforms the sound-based notification and the visual expression-basednotification whereas management computer 3 (management device) performsneither the sound-based notification nor the visual expression-basednotification. Only the visual expression-based notification may beperformed and the sound-based notification may not be performed in thesecond notification pattern as well. Even in this case, the remoteworker can appropriately recognize the occurrence of not remote responseerror ER but on-site response error EL.

As described above, notification units AM perform the notification inthe first notification pattern in a case where the type of the deviceerror is remote response error ER and perform the notification in thesecond notification pattern in a case where the type of the device erroris not remote response error ER based on the result of the device errortype determination in the error type determination process (ST1).

After the device error notification in the first notification process(ST2), the remote operation with respect to processing device MP inwhich the device error has occurred is carried out by the remote workernoticing the notification in management computer 3 (ST4: remoteoperation process). Then, it is determined whether or not the deviceerror in processing device MP has been eliminated through the remoteoperation by the remote worker (ST5: error elimination determinationprocess). In other words, it is determined whether or not the deviceerror has been removed from error information 31 a stored in managementstorage unit 31 by the device error in processing device MP beingeliminated by error type determination unit 33.

In a case where it is determined in the error elimination determinationprocess (ST5) that the device error has not been eliminated (No), theprocess proceeds to the second notification process (ST3) and thenotification in the second pattern is performed. In other words,processing device MP performs the notification in the secondnotification pattern in a case where the device error is remote responseerror ER and the device error has not been eliminated despitetermination of the remote operation by the management device subsequentto the notification performed in the first notification pattern by themanagement device (management computer 3). In other words, notificationunits AM perform the notification in the second notification pattern ina case where the device error is remote response error ER and the deviceerror has not been eliminated despite termination of the remoteoperation by the management device subsequent to the notificationperformed in the first notification pattern. Accordingly, a notificationurging the field worker to perform the on-site operation can beappropriately carried out even in a case where the device error cannotbe eliminated through the remote operation by the remote worker.

After the device error notification in the second notification process(ST3), the on-site operation with respect to processing device MP inwhich the device error has occurred is carried out by the field workernoticing the notification in processing device MP (ST6: on-siteoperation process). Accordingly, the device error elimination can beappropriately carried out through the on-site operation by the fieldworker even in a case where the device error cannot be eliminatedthrough the remote operation by the remote worker.

In component mounting system 1, it is determined whether or not thedevice error occurring in processing device MP is remote response errorER as described above, and notification units AM perform thenotification in the first notification pattern in a case where thedevice error is remote response error ER and perform the notification inthe second notification pattern in a case where the device error is notremote response error ER. Therefore, an appropriate notification can beprovided for the field worker or the remote worker supposed to deal withthe device error with respect to processing device MP constitutingcomponent mounting line L1, and the on-site operation by the fieldworker and the remote operation by the remote worker can beappropriately performed.

Hereinafter, a second example of the component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 6. The secondexample of the system operation method differs from the first example inthat the notification pattern is determined based on the presence orabsence of on-site operation right RL of processing device MP at a timewhen the device error has been detected. In the following description,the same reference numerals will be used to refer to processes common tothe first and second examples so that the same detailed description doesnot have to be repeated.

Once the device error is detected by device monitoring unit 23 ofprocessing device MP, error type determination unit 33 of managementcomputer 3 determines whether or not the device error is remote responseerror ER (ST1: error type determination process). In a case where thetype of the device error is remote response error ER (Yes in ST1),management side notification control unit 36 determines whether or noton-site operation right RL is set for processing device MP by referringto operation right information 31 b stored in management storage unit 31(ST11: on-site operation right determination process).

In a case where no on-site operation right RL is set for processingdevice MP (No in ST11), notification units AM perform the notificationin the first notification pattern (ST2: first notification process). Ina case where on-site operation right RL is set for processing device MP(Yes in ST11), notification units AM perform the notification in thesecond notification pattern (ST3: second notification process). In otherwords, in a case where the device error is remote response error ER andinput unit (input unit 25) of processing device MP is in operation at atime of the occurrence of the device error, notification units AMperform the notification in the second notification pattern.

In a case where it is determined in the error type determination process(ST1) that the type of the device error is not remote response error ER(No), notification units AM perform the notification in the secondnotification pattern (ST3: second notification process). After thedevice error notification in the first notification process (ST2), theremote operation with respect to processing device MP is carried out bythe remote worker (ST4: remote operation process).

Then, it is determined whether or not the device error in processingdevice MP has been eliminated through the remote operation (ST5: errorelimination determination process). In a case where it is determined inthe error elimination determination process (ST5) that the device errorhas not been eliminated (No), the process proceeds to the secondnotification process (ST3) and the notification in the second pattern isperformed. After the device error notification in the secondnotification process (ST3), the on-site operation with respect toprocessing device MP is carried out by the field worker (ST6: on-siteoperation process).

In component mounting system 1, it is determined whether or not thedevice error occurring in processing device MP is remote response errorER as described above, and notification units AM perform thenotification in the first notification pattern in a case where thedevice error is remote response error ER and perform the notification inthe second notification pattern in a case where the device error is notremote response error ER. In a case where the device error is remoteresponse error ER and input unit (input unit 25) of processing device MPis in operation at a time of the occurrence of the device error,notification units AM perform the notification in the secondnotification pattern.

In other words, in a case where the on-site operation is in progress inprocessing device MP, no notification is provided for the remote workerand a notification is provided for the field worker for response by theon-site operation even if the device error is remote response error ER.Therefore, an appropriate notification can be provided for the fieldworker or the remote worker supposed to deal with the device error withrespect to processing device MP constituting component mounting line L1,and the on-site operation by the field worker and the remote operationby the remote worker can be appropriately performed.

Hereinafter, a third example of the component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 7. The thirdexample of the system operation method, which is an appropriateoperation right control method for responding to the device error,differs from the first example in that remote operation right RR oron-site operation right RL is set for management computer 3 orprocessing device MP. In the following description, the same referencenumerals will be used to refer to processes common to the first andthird examples so that the same detailed description does not have to berepeated.

Once the device error is detected by device monitoring unit 23 ofprocessing device MP, error type determination unit 33 of managementcomputer 3 determines whether or not the device error is remote responseerror ER (ST1: error type determination process). In a case where thetype of the device error is remote response error ER (Yes in ST1),operation right setting unit 34 sets remote operation right RR formanagement computer 3 (ST21: remote operation right setting process). Inother words, in a case where the type of the device error is remoteresponse error ER, operation right setting unit 34 sets remote operationright RR with respect to the management device (management computer 3),remote operation right RR allowing the state to be achieved where theremote operation of processing device MP can be performed by the inputunit (input unit 37) of the management device.

Once on-site operation right RL is requested by acquisition button B3 ofprocessing device MP being operated thereafter in a state where remoteoperation right RR is set with respect to management computer 3 in theremote operation right setting process (ST21) (Yes in ST22), operationright setting unit 34 releases remote operation right RR (ST23: remoteoperation right release process). In other words, operation rightsetting unit 34 sets remote operation right RR with respect to themanagement device, remote operation right RR allowing the state to beachieved where the remote operation of processing device MP can beperformed by the input unit (input unit 37) of the management device(management computer 3). In the case of a request for an operation bythe input unit (input unit 25) of processing device MP thereafter in astate where remote operation right RR is set with respect to themanagement device, remote operation right RR set for the managementdevice is released.

Then, operation right setting unit 34 sets on-site operation right RLfor processing device MP (ST24: on-site operation right settingprocess). In this manner, remote operation right RR is released andon-site operation right RL is set, once a request for on-site operationright RL is made by the field worker, even after remote operation rightRR is set with the device error being determined as remote responseerror ER. Accordingly, the on-site operation by the field worker and theremote operation by the remote worker can be appropriately performed. Ina case where it is determined in the error type determination process(ST1) that the type of the device error is not remote response error ER(No), the process proceeds to the on-site operation right settingprocess (ST24) and on-site operation right RL is set for processingdevice MP.

In component mounting system 1, it is determined whether or not thedevice error occurring in processing device MP is remote response errorER as described above, and remote operation right RR is set for themanagement device (management computer 3) in a case where the type ofthe device error is remote response error ER. Accordingly, on-siteoperation right RL or remote operation right RR can be appropriately setand the on-site operation by the field worker and the remote operationby the remote worker can be appropriately performed.

In addition, in component mounting system 1, remote operation right RRset for the management device is released in the case of an on-siteoperation request in a state where remote operation right RR is set forthe management device (management computer 3). Accordingly, on-siteoperation right RL or remote operation right RR can be appropriately setand the on-site operation by the field worker and the remote operationby the remote worker can be appropriately performed.

Hereinafter, a fourth example of the component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 8. The fourthexample of the system operation method differs from the third example inthat on-site operation right RL is set for processing device MP in acase where idle time TA exceeds the predetermined period of time in astate where remote operation right RR is set. In the followingdescription, the same reference numerals will be used to refer toprocesses common to the first, third, and fourth examples so that thesame detailed description does not have to be repeated.

Once the device error is detected by device monitoring unit 23 ofprocessing device MP, error type determination unit 33 of managementcomputer 3 determines whether or not the device error is remote responseerror ER (ST1: error type determination process). In a case where thetype of the device error is remote response error ER (Yes in ST1),operation right setting unit 34 sets remote operation right RR formanagement computer 3 (ST21: remote operation right setting process).

Once it is detected by operation monitoring unit 35 that idle time TAhas exceeded the predetermined period of time and the predeterminedperiod of time has elapsed since the final remote operation in a statewhere remote operation right RR is set with respect to managementcomputer 3 in the remote operation right setting process (ST21) (Yes inST31), operation right setting unit 34 releases remote operation rightRR (ST23: remote operation right release process). In other words,operation right setting unit 34 releases remote operation right RR in acase where no remote operation by the management device (managementcomputer 3) is performed for the predetermined period of time in a statewhere remote operation right RR is set for management computer 3.

Then, operation right setting unit 34 sets on-site operation right RLfor processing device MP (ST24: on-site operation right settingprocess). In this manner, remote operation right RR is released andon-site operation right RL is set, even after remote operation right RRis set with the device error being determined as remote response errorER, in a case where the remote operation by the remote worker is notperformed for the predetermined period of time. Accordingly, the on-siteoperation by the field worker and the remote operation by the remoteworker can be appropriately performed. In a case where it is determinedin the error type determination process (ST1) that the type of thedevice error is not remote response error ER (No), the process proceedsto the on-site operation right setting process (ST24) and on-siteoperation right RL is set for processing device MP.

In component mounting system 1, it is determined whether or not thedevice error occurring in processing device MP is remote response errorER as described above, and remote operation right RR is set for themanagement device (management computer 3) in a case where the type ofthe device error is remote response error ER. Remote operation right RRis released in a case where the remote operation based on the managementdevice is not performed for the predetermined period of time.Accordingly, on-site operation right RL or remote operation right RR canbe appropriately set and the on-site operation by the field worker andthe remote operation by the remote worker can be appropriatelyperformed.

Hereinafter, a fifth example of the component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 9. The fifthexample of the system operation method differs from the third example inthat on-site operation right RL is set for processing device MP in acase where the specific operation has been performed in processingdevice MP in a state where remote operation right RR is set. In thefollowing description, the same reference numerals will be used to referto processes common to the first, third, and fifth examples so that thesame detailed description does not have to be repeated.

Once the device error is detected by device monitoring unit 23 ofprocessing device MP, error type determination unit 33 of managementcomputer 3 determines whether or not the device error is remote responseerror ER (ST1: error type determination process). In a case where thetype of the device error is remote response error ER (Yes in ST1),operation right setting unit 34 sets remote operation right RR formanagement computer 3 (ST21: remote operation right setting process).

Once it is detected by device monitoring unit 23 that the specificoperation set in advance in processing device MP has been carried out ina state where remote operation right RR is set with respect tomanagement computer 3 in the remote operation right setting process(ST21) (Yes in ST41), operation right setting unit 34 releases remoteoperation right RR (ST23: remote operation right release process). Inother words, operation right setting unit 34 releases remote operationright RR set for the management device (management computer 3) in a casewhere the specific operation set in advance has been performed withrespect to processing device MP in a state where remote operation rightRR is set with respect to the management device (management computer 3).

The predetermined specific operation is an operation relating to thesafety of the field worker and is at least any one of the opening andclosing of safety cover 7 of processing device MP (component mountingdevices M5 to M8), the operation of stop button B2 of processing deviceMP, the attachment and detachment operation for tape feeder 8 (componentsupply device) or batch replacement carriage 9 installed in processingdevice MP.

Then, operation right setting unit 34 sets on-site operation right RLfor processing device MP (ST24: on-site operation right settingprocess). In this manner, remote operation right RR is released andon-site operation right RL is set, even after remote operation right RRis set with the device error being determined as remote response errorER, in a case where the predetermined specific operation has beenperformed in processing device MP. Accordingly, the on-site operation bythe field worker and the remote operation by the remote worker can beappropriately performed. In a case where it is determined in the errortype determination process (ST1) that the type of the device error isnot remote response error ER (No), the process proceeds to the on-siteoperation right setting process (ST24) and on-site operation right RL isset for processing device MP.

In component mounting system 1, remote operation right RR set withrespect to the management device is released as described above in acase where the specific operation set in advance has been performed withrespect to processing device MP in a state where remote operation rightRR is set with respect to the management device (management computer 3).Accordingly, on-site operation right RL or remote operation right RR canbe appropriately set and the on-site operation by the field worker andthe remote operation by the remote worker can be appropriatelyperformed.

Hereinafter, a sixth example of the component mounting method forcomponent mounting system 1, which is a system operation method forappropriately operating management computer 3 and processing device MPin response to the device error occurring in processing device MP, willbe described with reference to a flow illustrated in FIG. 10. The sixthexample of the system operation method differs from the third example inthat the remote worker in a state where remote operation right RR is setintentionally releases remote operation right RR set for himself orherself from management computer 3 side and sets on-site operation rightRL for processing device MP. In the following description, the samereference numerals will be used to refer to processes common to thefirst, third, and sixth examples so that the same detailed descriptiondoes not have to be repeated.

Once the device error is detected by device monitoring unit 23 ofprocessing device MP, error type determination unit 33 of managementcomputer 3 determines whether or not the device error is remote responseerror ER (ST1: error type determination process). In a case where thetype of the device error is remote response error ER (Yes in ST1),operation right setting unit 34 sets remote operation right RR formanagement computer 3 (ST21: remote operation right setting process).

In a case where the remote worker is to transfer his or her operationright to processing device MP for a reason such as incapability of errorelimination by the remote operation in a state where remote operationright RR is set with respect to management computer 3 in the remoteoperation right setting process (ST21), operation right setting unit 34releases remote operation right RR through an operation (ST51) ofmanagement computer 3 by the remote worker (ST23: remote operation rightrelease process).

Then, operation right setting unit 34 sets on-site operation right RLfor processing device MP (ST24: on-site operation right settingprocess). By this operation being performed, the on-site operation bythe field worker and the remote operation by the remote worker can beappropriately performed. In a case where it is determined in the errortype determination process (ST1) that the type of the device error isnot remote response error ER (No), the process proceeds to the on-siteoperation right setting process (ST24) and on-site operation right RL isset for processing device MP.

Although an aspect in which error type determination unit 33 andoperation right setting unit 34 are disposed only in management computer3 has been described in the present exemplary embodiment, similarfunctions may also be provided in each processing device MP as errortype determination unit 33P and operation right setting unit 34P asillustrated in FIG. 11. In addition, each processing device MP mayperform the notification based on a notification pattern stored indevice storage unit 22 of itself and based on a result of determinationby error type determination unit 33P of itself with the notificationpattern being stored in device storage unit 22 of itself while eachprocessing device MP provides a notification pattern instruction formanagement computer 3 and sets the operation right by using operationright setting unit 34P if necessary.

In addition, each of respective processing devices MP and managementcomputer 3 may perform determination with error type determination unit33 or error type determination unit 33P of itself based on errorinformation 31 a and determine a notification pattern to be performed byitself.

According to the above description of the present exemplary embodiment,the power supply to processing device MP is disconnected and processingdevice MP is emergency-stopped once emergency stop button B4 isoperated, but the present disclosure is not limited thereto and theoperation of processing device MP may be stopped without, for example,the power supply being disconnected. Although tape feeder 8 has beendescribed as the component supply device in the present exemplaryembodiment, the present disclosure is not limited thereto and varioustypes of component supply devices such as a tray feeder, a stick feeder,and a bowl feeder may take its place. These component supply devices maybe directly attached to and detached from processing device MP or may beattached to and detached from processing device MP via batch replacementcarriage 9. As a matter of course, the specific operation includes theattachment and detachment of these component supply devices.
